Application filed January 2a, 1926. Serial m. 83,102. a

This invention relates to means for facilitating the renewal of thetransmission bands in the Ford type of motor vehicle, the general objectof the invention being to pros videmeans for drawing a band around itsThis invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafterf-ully described, il-

v lustrated in the accompanying drawings and specifically pointed out inthe appended claims. 1

In describing my invention in detail, reference will be had to theaccompanying,

drawings wherein like characters denote like or corresponding partsthroughout the s eve v eralviews, and in which Fig. 1 is a sectionalview through a trans,

2'0 mission means showing a spring member "being used to place a band onits drum.

Fig. 2 is a similar view showing another step in the operation.

Fig. 3'is a View of the spring member. Fig. 4; is a partial view of theband. 7 "Fig. 5 is a view of thedetachable ear therefor. j l

As is well known, the Ford type of motor includes in its transmissionthe drums 1 and the bands 2, each band having a detachable ear 8 whichhas key-hole shaped slots 4: therein for engaging the headed studs 5 onthe band and a round hole 6 for receiving a rivet 7 .on the band; Thisend of each band is also provided with a hole 8.

lVhen a band is to be removed, this ear is removed and then the othercar seized and the band pulled from around the drum. In replacingtheband or a new one, the end serted between the transmission casing andthe drum, after the upper part ofthe case has been removed, and a toolmust be used to fish for the band if the band .fails'to'be thereof whichcarries the detachable ear'is inguided by the flanges of the drum as itis 10 which is adapted to eng f headed studs5 oftheband. The other endof the, strip B is bent upon itself, as shown at11.

When a band is to be removed and then the ear-is'removed from the bandby a suitable tool. The band is then seized by its other ear and pulledfromaround the drum. The tab 9 of the member B is then connected withthe new band or the old one if this is to be replaced, by placing theslot 10 over one of the headed studs 5 of the band. The end 11 of thespring strip B is then placed on the drum andthe I removed, the nut andwashers are taken ofi the shaft and the shaft strip pushed upon to causeit to pass around the drum as shown in Figure l. The strip is thenpulled around the drum, and as the band is attached thereto, the bandwill also and a part of the casing, when further move- ,mentwill beprevented. This will bring the. other end of the band at'the top of thedrum.-

The tab 9 is moved to one side so as to ex-s pose theiopening 8 and thena tool is placed in said. opening. -The tab is then removed from thebandand the studs 5.

Fromthe foregoing, it Waite seenlthat I have provided simple meanswherebythe' transmission bands can be easily removed from and replacedonthe drums through the inspection opening and Without removingthe upperportion of the transmission case. As will be seen from the drawings, bymakthe ear 3 placed over be pulled around'the drum, as shown in ure 2.The band is pulled around the drum. untilits permanent ear engages thedrum ing the band or strip B of spring metal, its.

tension will cause it to coil upon itself and thus it will follow thecontour ofthedrum as it is pushed over the same so that there i is nodanger of the .band being checked in its movement from any part. of thetrans mission casing. V I

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent. I desire it tobe understoodthat I may make changes in the construction and in thecombination and arrangement of the several I v 7 parts, provided thatsuch'changes fall within the scope of the appended claims.

Vvhat I claim is I 1. A tool for facilitating the removal of atransmission band from a transmission drum comprising a strip or bandformed ot L insane, I

spring metal and means at one end of the band for detachably engaging apart of a transmission band to connect the said transmission band to thetool, the tension ot the spring strip causing it to follow the contourof the drum as the strip is pushed over the drum. i r

'2. A tool for facilitating the removal or a brake band from atransmission drum comprising a spring strip and a tabhinged to one endthereof so that it can move about an axis which is at right anglesto'the length of the strip and said tab having a slot therein,thetensionof-the spring strip causing it A class described, a predeterminedlength of to follow the contour of the drum as the strip is pushed overthe drum. 7 i

3. Ina transmission band installer of the i normally coiled flexiblematerial adapted'for forcible engagement around a drum of thetransmission, one end of said length of mate rial being adapted fordetachable connection to one endof the transmission band beinginstalled, the other end of the length of material providing ameanswvhereby the same may be moved around the drum for position-"ingthe transmission band on the drum, the

length of the material being removed from the band when the latter is inits proper position.

4. In a transmission band installer of the class j described, anelongated strip of nor- 7 mally coiled spring metal adapted reefercibleengagement around the drum of the transmission, a hook at one end ofsaid strip adapted for detachable engagement with one end of thetransmission band, the other end, of the strip providing a handleportion whereby the strip may be moved around the drum for positioningthe transmission band thereon, said hook beingdisengaged from thetransmission bandwhen the latter is in proper position.

5. In a transmission band installer of the class described, anelongatedstrip of nor mally' coiled spring metal adapted for for cible engagementaround the drum of the strip may be moved around the drum for po'sitioning the transmission" band thereon,

mission band When the. latter'is in proper position around the drum,

6. A tool for inserting a band around a 'transmisssion drum on anautomobile, com

prising a resilient member of less curvature thanthe curvature of thedrum, and pro+ vided at one end with means'adapted for vdetachableconnection with one end of the 'band. l v r '7. A tool for inserting aband around a transmission drum of an automobile, comthanthe curvatureof the drum, and provided at one end with a slot for detachablyconnecting with one end of the band.

8. A tool for inserting a band around a' '55 said hook being disengagedfrom the transprising a resilient member of less curvature Vtransmission drum of an automobile, compris ing a resilient member ofless curvature than V the curvature of the drum and of substantially theWidth of the band, and provided at one end with manual gripping meansand at the other end With a slot for detachably connecting with one endof the band.

In testimony whereof I aiii'x my signature.
